You scheduled your mail merge, and you realize your emails are not sent yet.

Several reasons can explain this issue:

• YAMM cannot deliver your scheduled emails if you deleted either the draft in Gmail or the Google sheet.
  
  info  If you modify your draft before the scheduled time, YAMM will send the latest version
• The delivery time is an estimated time, and YAMM checks your Google sheet every 30 minutes. It can take up to 30 minutes after the time you specified for your mail merge to be sent.
• Your scheduled mail merge stopped because of your limited quota.
  For example, if you have 130 recipients remaining quota and your scheduled mail merge contains 200 recipients; your mail merge will stop after sending emails to 130 recipients and will automatically send emails to the remaining 70 recipients around 24 hours later, when your quota resets.
